Application filed March 22, 1924. serial No. 701,015.r

The invention provides an improved mac- Verating* machine and has particular reference to |`spray nozzles for such niachineswhereby te be` capable o f use for various purposes, one being for use in connection with sugar cane mills, for saturating a traveling blanket ofbagasse either with water or'juice ofr a' mixture of both thereof, and I will describe the construction and operation of my invention as applied to useA for saturating bagasse on its travel betweenV thesuccessive sets of expressing rollers of a sugar cane mill. n f

,It isto be understood, however, that I do not coni'ine the nozzle of my vinvention to use for saturatingbagasse, because the nozj zle is also adapted for usel 'as a sprayer in other associations, as, for illustration,spray iro'afdsI or streets,` watering gardens or grass plots and spraying disinfectant and germ' exterminating solutions', and for analogloiis uses.

to provide in a macerating machine having a series of discharge4 nozzles for the water or, juice, conveniently operated meansQ-for etliciently and quickly cleaning the orifices of said nozzles, thereby ensuring a proper flow through the same and the perfect saturation of the hagas-se.

further object ofthe invention is" to provide such devices of reliable and durable character throughout and composedof easily assembled parts,l and which'will ybe capable of Beingreadily positioned-for useand convenieiitlyoperated'.y Further purposesof the invention willappear hereinafter in connection the description of the construction Iiiachine.

cured the brackets 22. The standards 24 are Y in pairs at each end of the machine and said standards receive between themand serve as guides for the ends of the vertically movable bar 16 and end portions of the longitudinally shiftable bar 20. The standards 24 likewise receive between them the. ends of the stationary bar 19, which ends are rigidly The manifold is connected with the stationary bar 19 by means of yokes or hangers 25. y Y

Upon Vthe, stationary vbar 19 is pivotally mounted a series of corresponding pairs of bell-crank levers 26 whose upwardlyy extending arms are pivotallyV secured to the shiftable bar 2O and whose other arms are pivshorter arms to lift the links 27 andthereotally connected with the pairsof links 27, one link of each pair being Aat each side of the bars 16, 19 and 20, and saidlinks being pivotally secured to the bar 16 by bolts 28 (Fig. 3) and freely straddling the bars19, 20. The links 27 of each pairthereof are connected together below the bar 2O by bolts 29 and above said bar byA bolts 30, suflicient clearance being left between the bolts 29, 30 for the necessary movement of the bar 2O (Fig. 3). i

,Y When the bar 20 is moved endwise in one direction by an attendantoperating one-of the levers 21,v theV bell-crank levers 26 are turned on their pivots and act through their through the bar 16 and series of' rods 14 with their cleaning blades 15, this being the position of the parts shown in the drawings,

(Figs. 3 and 4),*saidtip'preferably, for ac- ,Curacy and convenience vin manufacture, being in a separate piece and threaded upon or otherwise. secured to the lower end of said body part 31. The tip 32 is of cup-shape andi contains a segmental discharge slot or elongated orifice 33 whose length is parallel Vwith the length of the manifold 10. The

body part 31 of eachnozzle is threaded, at

34, to screw into a tapped nozzle-hole 35 in the manifold 10, and' each ofthe nozzles-extends upwardly into the manifold a substantial distance above the lower inner surface vthereof for the purpose of excluding there- `from to a great extent the dirt and scale that may gather within the manifold. Each ynozzle has a hexagonal shoulder 36 tore- -ceive a wrench-to be used in applying the nozzle to the manifold.v The body-part 3l of cach nozzle has a vertical cylindrical bore and at opposite sides thereof vertical grooves 37 (Figs. 4 and 5.) within which are placed the opposite vertical edges of the vertically movable cleaning blade 15, said blade vduring its movements being guided in said grooves and being at all times held inv correct position within the nozzleby said grooves. The blades 15 valways remain within the nozzles and they are thin and flat so as not to unduly obstruct the iow through the'nozzles. .The blades 15 are about the samein width as the length ofthe orifices 33, as indicated by the dotted linesy in Fig. 4, and said blades when moved to their lower position may extend through and4 effectually clean said orifices. Y The blades 15 are rigidly secured to the lower ends of the rods 14, hereinbefore referred to, which extend upwardly through glands 36 at the top'of the manifold 10, all the rods 14 being alike and all being connected with the aforesaid bar 16. y. The flush-valves 13. normally close openf ings 39 (Fig. 7 in the bottom of theamanifold 10 and said valves are secured on the lower ends of rods 40 which extend upwardly through glands 4l at the top of the manifold and have on their upper ends upwardly ex-` tending forks 42 which straddle the lower edges of the bar 16. The rods 40 alsohave upon their upper portions the-coiledsprings 43 whose tension normally seats the valves 13. Thesprings 43 areconiined betweenl the glands 41 and washers 44, which are held in suitably adjusted position by means of nuts 45. 1, Y

The drawings illustrate thel parts ofthe machine vin normal operative position, the Ablades 15 being in their upper position and the valves 13 being closed. The liquid, under pressure, flows from the supply pipe 11 into the manifold 10 andthence issues against the bagasse, not shown, through the segmental-slots 33 of the series of nozzles 12,

Vthe liquid discharging` in divergng overlapping sprays or streams, as indicated by Vdotted lines in Fig. .1, and therebyforming .a sheet ofy liquid spray extending transversef ly across the body of traveling .bagasse After the machine has been in operation for a length of time, the discharge oriiices 33 may become clogged and the manifold l0 may require cleansing, and under this condition the bar 20 willbe shifted toward the left, looking at Fig. 1, by force applied thereto from one or the otherk of thelevers 21 or otherwise, and thefresult off-this movement of the bar 2O will be that the bellcrank levers 26, acting through the links 27, will depress the bar 16 `and rods 14 and thereby cause all of the blades 15 to descend through the nozzlesV 12 and pass, at their lower ends, into and through the orilices 33, thereby clearing said orifices of any matter lodged therein and clogging them. `The blades snugly lill the orifices 33, having a clearance from the Walls thereof of only about .003 of an inch. The bar may be shifted back and forth several times in succession, if found necessary, to reciprocate the blades 15 through the orifices 33 for the purpose of clearing them of foreign matter. The depression of the bar 16 may also be utilized to act on the rods and open the flush-valves 13, thereby permitting the cleaning out of the manifold 10. After the oriiices 33 have been cleared and it is desired to resume the operation of the machine, the bar 20 Will be returned to its position shown in Fig. 1, this causing the bell-crank levers 26 to effect the elevation of the bar 16 rods 14 and cleaner-blades, said blad-es then retiring to their upper position, shown in Figs. 3 and 4, and the valves 13 closing under the tension of the springs 43.

I have hereinbefore described the application of the spraying nozzle of my invention to the saturation of bagasse, but as hereinbefore indicated I do not confine the invention to use in sugar cane mills, since the device is useful for spraying roads or streets, Watering gardens and the like and spraying disinfectant and germ exterminating solutions and for other or analogous purposes.

I have presented my invention herein as embodied in the most satisfactory form of machine at this time known to me, but I do not limit my invention to all of the details of arrangement and construction shown and 35 described, since I am aware that these details admit of modification Without departure from the spirit of my invention or the scope of the appended claims.

What I claim as my invention and desire to secure by Letters-Patent, is

1. In a spraying nozzle for macerating machines, a body portion having a cylindrical bore, sides of the bore, a. thin blade adapted to slide in said grooves, a rod attached to the blade, a detachable tip provided with an elongated slot and means for reciprocating the blade in the grooves and slot.
